android - EditText 没有关注带有 NestedScrollView 的 CoordinatorLayout
问题描述
我有一个不允许聚焦和输入的 EditText。屏幕具有 CoordinatorLayout 作为根/父级和带有 ViewPager 的 NestedScrollView。
顶部有谷歌地图，底部有两个标签。
第一个选项卡包含带有 EDIT TEXT 的文本内容（有问题），第二个选项卡上有一个 recyclerview。
使用此布局无法在第一个选项卡上的 EditText 上进行聚焦和键入。

解决方案
您可以强制编辑文本以编程方式获得焦点。在您的 TAB1 java 类中，您可以执行以下操作来强制编辑文本获得焦点。
EditText editText = findViewById(R.id.test_text); //initialize edit text
editText.requestFocus(); //will request focus
//will force the keyboard to show
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(editText, InputMethodManager.SHOW_IMPLICIT);
